Robert McCulloch, Fort William,

Ontario, Canada Claims.

This present invention relates to certain new and useful improvements ina shoe.

The primary object of the invention resides in the provision of a shoewhich is of improved construction and gives more comfort to the wearerthan the shoes now in general use.

The invention has for another object the provision of a shoe of thecharacter stated in which the sole is improved and constructed in such amanner as to prevent the formation of lumps or ridges in the toe andcurling up of the edge of the insole.

The invention has for a further object the provision of a shoe of thecharacter stated in which the sole is constructed to permit a doubleflexing thereof during walking and thus supporting the arch of the footin a natural manner.

The invention has for a still further object the provision of a shoe ofthe character stated having a sole which is flexible throughout itsentire length and substantial in construction, thus forming a soft butfirm support for the sole of the foot while the shoe is worn.

The invention has for a still further object the provision of a shoe ofthe character stated in which the entire inner sole is flexible and freefrom lumps or curled edges during the entire life of the shoe, thuspresenting a flexible smooth support for the sole of the foot while thewearer is standing or walking and thus providing a shoe which will notcause an uneven pressure against nerves of the foot or cause thedevelopment and formation of callouses or other foot troubles.

A still further object of the invention resides in the pro-vision of ashoe of the character stated in which the improved insole structure maybe readily incorporated in the shoe without materially altering thestyle or formation of the shoe.

The invention has for a still further object the provision of a shoe ofthe character stated which will not only give the desired smooth supportfor the sole of the foot and permit free double flexing of the solewhile walking to gently massage the bottom of the foot withoutirritating the same but will also absorb moisture from the foot withoutin turn causing absorption of leather dyes and the like by the foot, asoccurs at the present time with any type of shoes now in general use.

The invention has for a. still further object the provision of a shoe ofthe character stated which may be manufactured at a reasonable cost andsold at a popular price with good profit, thus providing a commerciallyattractive proposition.

To the accomplishment of these and related objects as shall becomeapparent as the description proceeds, my invention resides in theconstructon; combination and arrangement of parts as shall behereinafter more fully described, illustrated in the accompanyingdrawing and pointed out in the claims hereunto appended.

The invention will be best understood and can be more clearly describedwhen reference is had to the drawing forming a part of this disclosure,wherein like characters indicate like parts throughout the severalviews.

In the drawing:-

Figure 1 is a bottom plan of the improved inner sole for the shoe;

Figure 2 is a longitudinal vertical section through the complete shoewith the improved inner sole incorporated therein; and

Figure 3 is a transverse vertical section, taken substantially on theplane of line 3-3 of Figure 2, looking in the direction indicated by thearrows.

Referring more in detail to the drawing, it is to be noted that theinsole E is composed of chrome tanned cowhide or other appropriatematerial which will not crack or curl up at the edges. The underlining Iof leather is stitched in the usual Way to the insole and the edge 8thereof turned down, except at the heel portion. This underlining T iscovered with canvas 9, except at the flat heel portion and the channelformed under the ball and instep portion by turning down the edge 8 ofthe underlining l is filled with a single strip of sheet cork I!) heldin place around its edges vn'th a compound of cork and tar i i. Thus thestrip of sheet cork It and canvas 9 are interposed between the insole 6and the outer sole l2, which is secured in place in the usual and wellknown manner. The welt strip I3 is also mounted suitably on the upperface of the outer sole l2, along the forward end and side edges thereofto the heel portion of the shoe. The shoe upper I4 is brought down andturned under between the outer sole l2 and the edge of the insole 6 andsecured thereto by stitching or other appropriate means. The welt stripI3 may then be readily secured on the outer sole 52 by stitching orother means. The remainder of the shoe may be assembled and finished inany suitable or appropriate manner.

As the construction of the device has thus been described in detail,brief reference is now had to its use and modus operandi: This shoestructure provides a smooth soft sole which is exceptionally flexibleand pliable and remains in that condition throughout the life of theshoe. By applying the chome tanned cowhide for the inner sole 6, thecanvas covering 9 for the underside and the single strip of sheet corkI0, the shoe sole will not work into lumps or ridges under the foot and.curling up of the edges of the inner sole 6 is also impossible. Thiscombination and arrangement of co-operating elements for building up thesole of the shoe also permits a double flexing of the inner sole 6 asthe heel is raised and the weight of the wearer thrown onto the ball ofthe foot in walking. As the toe of the shoe turns up by the weight ofthe wearer resting on the ball portion of the foot, the intermediate orinstep portion of the inner sole 6 rises, slightly and gently massagingthe instep on the bottom of the foot and supporting the same withoutirritating the foot. Excessive moisture from the foot is absorbed by thechrome tanned cowhide inner sole 6 without absorption into the foot ofleather dyes and impurities. The single strip of cork I 0 serving as thefiller between the inner sole 6 and the outer sole I2 retains its shapeand character throughout the life of the shoe and does not work up intolumps or ridges but permits the foot to have a smooth even support underthe sole of the foot, the entire length and width thereof. Furthermore,as it is impossible for the edge of the chrome tanned cowhide 6 to curlup at the edges either when being worn or when the shoe is temporarilylaid aside, it is thus impossible for the shoe to develop raisedportions within the same along the edge of the inner sole 6.

From the foregoing description taken in connection with the accompanyingdrawing, it will be manifest that a shoe is provided that will fulfillall the necessary requirements of such a device but as many changescould be made in the above descriptiomand many apparently widelydifferent embodiments of my invention may be constructed within thescope of the appended claims without departing from the spirit or scopethereof. It is intended that all matters contained in the saidaccompanying specification and drawing shall be interpreted asillustrative and not in a limited sense.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a shoe structure, a double flexing chrome tanned leatherinner-sole having a noncurlable edge, a leather pocket with a downturnededge under said chrome tanned inner-sole, a flanged canvas coverunderlining for said leather pocket, a single strip sheet cork fillerheld in said canvas lined pocket, a welt stitched to said inner-sole,and an outer sole stitched to said welt and contacting with said singlestrip sheet cork filler.

2. In a shoe structure, a double flexing inner sole comprising a singlestrip sheet cork member, surrounded on its top and edges by a canvasliner and a chrome-tanned leather insole with a leather under-pieceflanged around its edges to provide a pocket in which said canvas issecured; and an outer sole covering said sheet cork member and theperimeters of said flanged leather underpiece and canvas lining.

3. In a shoe structure, a double-flexing chrome tanned leather insole,an inverted leather pocket underlying the same and on which said chrometanned leather insole is supported, a canvas lining for said pocketflanged downwards around its edges engaging the entire interior surfacesof said pocket, and a single strip sheet cork filler held in saidflanged canvas lining.

4. In a shoe structure, an inner sole comprising a leather pocketsurfaced with a double flexing piece of chrome tanned leather, saidpocket being inverted, a canvas lining for said pocket flanged downwardsaround its edges engaging the entire interior surfaces of said pocket,and a single strip sheet cork filler held in said flanged canvas linlng.

5. In a shoe structure, in combination with an upper, a welt and anouter sole; an inverted leather pocket; a canvas lining therefor and asheet cork filler in said canvas lined leather pocket; and a doubleflexing chrome tanned leather insole overlying said inverted cork filledcanvas lined leather pocket and extending beyond the perimeters thereofto overlie and be stretched to the inturned lower edges of said upper.
